MAGNETIC PISTONS ENGINE

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the bene?t of US. provisional patent application Ser. No. 60/813,259 ?led Jun. 12, 2006.

FIELD OF THE INVENTION

The present invention relates to the “Magnetic pistons engine”, hereafter called “Maps engine” or “RAT engine” or “engine” that Works on the principle of magnetism. It can be used to perform various tasks and functions that involve application of force or displacement of objects. This method provides an environmental friendly, very high e?iciency engine that can complement or replace any engines that use fossil fuel, bio-fuel, solar poWer, Wind poWer, hydro poWer, electricity, stored energy, or other energy sources.

BACKGROUND OF THE INVENTION

Generating linear or circular motion poWer using different technologies is knoWn for centuries. There are many types of engines to accomplish this. Internal Combustion engines and Steam engines are feW examples of linear reciprocating engines. While Internal Combustion engines mainly use fos sil fuel steam engines use hydro poWer. In all such engines, the reciprocating motion generated by the linear movement of one or more pistons is converted to the circular motion With the help of a crankshaft assembly. The engine is generally integrated Within the main product (or machine) and serves as the heart of the equipment. Such an engine can be used as an automobile engine, aircraft engine, locomotive engine, ship engine, poWer generator engine, etc.

With the diminishing fossil fuel resources and unabated increase in energy costs and environmental concerns, engines using alternate energy sources such as bio-fuel, solar poWer, Wind poWer, electric poWer, stored poWer, etc. are being developed around the World. HoWever, such engines have many limitations. Production of bio-fuel takes enormous resources and they still pollute the environment. They do not meet the ever increasing energy demand as Well. Engines that use storage poWer sources like batteries or compressed air have energy density issues. Similarly, the solar poWer is not e?icient. Added to all, the initial capital and subsequent main tenance costs for machines that use alternate energy sources are very high. Further, the electricity that is used to charge the batteries or to re?ll the compressed-air tank may be produced from a thermal poWer plant that is again a concern for envi ronmental pollution. Hence, in the absence of a viable alter native, until noW, sWitching to neW technology by changing from traditional Internal Combustion engines has been a chal lenge.

BRIEF DESCRIPTION AND SUMMARY OF THE INVENTION

The invention of Magnetic pistons engine, also called Maps engine, RAT engine, or engine, shoWn in FIG. 1, gen erally relates to the reciprocating engine based on linear, back-and-forth movement of the pistons and the improve ments thereto. The uniqueness of this invention comes from the fact that Maps engine can be effectively integrated With equipments and machines that need engine to perform various tasks and functions. It can Work as an automobile engine, aircraft engine, locomotive engine, ship engine, laWn mover

2 engine, etc. depending on the requirement. In general, it can complement or replace existing engines that use fossil fuel, bio-fuel, electric poWer, solar poWer, Wind poWer or stored poWer, etc. Further, it can also be used to drive the poWer generators to produce the electricity. The use of Maps engine is limitless When the application area is considered.

Unlike Steam engines and Internal Combustion engines, Maps engine is environmentally very safe since it does not burn any fuel. Due to the rising fuel costs, environmental issues and diminishing natural fuel reserves, Maps engine can become a viable alternative to many existing engines.

Further, due to the principle of its operation, Maps engine uses very loW poWer (small force) to generate very high poWer (large force). Hence, Maps engine Works at very high e?i ciency With the possibility of reaching unity-over operation mode.
